10. A method, comprising:
starting a lane guidance system of a vehicle;
determining that all constraints for the lane guidance system are satisfied other than a user request to activate the lane guidance system;
receiving a user request to activate the lane guidance system;
outputting, responsive to receiving the user request, a request for the user to touch a steering handle of the vehicle;
determining a time period from a time of the request for the user to touch the steering handle until a touch from the user on the steering handle is detected;
comparing the determined time period with a predetermined time window; and
blocking, responsive to the determined time period being greater than the predetermined time window, an activation option of the lane guidance system responsive to a first request to touch the steering handle after an idle state of the vehicle,
wherein the activation option is blocked until, and the lane guidance system is no longer available until, a subsequent idle state of the vehicle.
